| Abstract: | Bioassay method was used to study the biological activity of different polar solvent extracts of False ragweed seed. Specially, water extracts of False ragweed has an effect on plant germination and root length. The study found that False ragweed seed extracts had different degrees of inhibition on many plant seed germinations, and inhibited the germination of cucumber seeds best, the maximum inhibition rate was 79.5%, for cabbage, sorghum and maize seed germination inhibition rate was more than 30%. False ragweed seed extracts also had strong inhibition on cucumber and many other plant root length, and inhibited the root length of cucumber best followed by red beans. The result showed that False ragweed seed extracts contained some materials that could inhibit germination and growth of some plants. |
